ZADOCK MCVAY, OF DOUBLEEl SPRINGS, ALABAMA.

ACETYLENE-GAS GENERATOR.

To all whom it may concern Be it known that I, ZADOCK MoVAY, a citizen of the United States, residing at Double Springs, in the county of Winston and State of Alabama, have invented certain new and useful Improvements in Acetylene- Gas Generators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to acetylene gas generators and has for its object the production of an efficient carbid feed means for a generator whereby the carbid may be delivered to the water in measured quantities.

Another object of this invention is the production of an eflicient means for sud denly releasing the delivering valve for the carbid chamber.

With the above and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings :Figure 1 is a vertical section of the generator. Fig. 2 is a section taken on line 22, of Fig. 1. Fig. 3 is a section taken on line 33, of Fig. 1. Fig. 4 is an enlarged sectional view through the lower end of the carbid container showing the delivering valve in a closed position. Fig. 5 is a view similar to Fig. 4 showing the valve in an open position. Fig. 6 is an enlarged sectional view showing the means for attaching the operating rod to the gas bell. Fig. 7 is abottom plan view of the structure shown in Fig. 6. Fig. 8 is a top plan view of the latch member which normally supports the tripping trigger which controls the delivering valve of the carbid container. Fig. 9 is a side elevation showing the connection of the bracket which supports the releasing trigger, with the carbid container. Fig. 10 is an enlarged sectional view of the filter carried by the discharge spout.

By referring to the drawings it will be seen that 1 designates the main casing of the generator which is provided with a. clean out opening 2 at its opening, which clean out opening is normally closed by means of the threaded plug 3. The casing 1 is provided with a centrally located cylinder 4 which is connected to the outer casing 1 by means of an angularly extending flange 5. This cylinder 4 is spaced from the side walls of the casing 1 and the space between the cylinder Specification of Letters Patent.

and the side wall of the casing 1 is filled with water to constitute a water seal for the gas bell 6.

The gas bell 6 is formed of the usual type and is provided at its upper end with an opening 7, said opening 7 being normally closed by means of a closure cap 8 which cap carries a rubber sealing washer 9 upon its lower face to prevent the escape of gas therefrom. A supporting bracket 10 engages the inner face of the gas bell 6 and extends across the opening 7 and constitutes a guide for the operating rod 11. This operating rod is threaded at its upper end as indicated at 12 and is held in an adjusted position by means of a threaded nut 13. The gas bell 6 works between the cylinder 4 and the outer casing 1 in the usual manner as is the case with the water seal. The cap 8 and bracket 10 may be swung so as to allow the insertion of a funnel therein for the purpose of filling the carbid tank 14 through the filling opening 15. This carbid tank 14 is placed within the cylinder 4 and is normally held thereon by means of the spring supporting bracket 16. Spacing spring members 17 are also carried by the tank 14 to hold the carbid tank 14 in spaced relation relative to the cylinder 4. A gas outlet pipe 18 passes vertical of the water seal chamber and carries a filter 19 at its upper end. This filter 19 is provided with a fibrous filling 20 for the purpose of absorbing the dampness from the gas as the same passes from the supply or delivering pipe 18. The delivering pipe 18 may be conveyed from the easing 1 to the source of consumption in any desired manner.

The carbid tank 14 comprises an elon ated body having a substantially conical s ape lower end 21 and this end is provided with a reduced discharge neck 22. The lower end of this neck is provided with a rubber washer 23 for constituting an eiiicient closure for air tight joint when the conical closure valve 24 is brought into engagement therewith to prevent the dampness from entering through the discharge aperture 22 into the carbid container 14. This conical valve 24 is carried by a vertical sliding sleeve 25, which sleeve is provided with a laterally extending collar 26 engaging the lower end of the collar 27 of the conical valve 24. This collar 27 is engaged by means of the flexible latch member 28 which carries a spring 29 for normally holding the same in engagement with the collar 26. By means of the latch member 28 the valve will be firmly held in a closed position and will not be released until the sliding head 30 moves downwardly upon the latch 28, and kicks the same from under the flange 26. This head 30 is carried by a vertically extending rod 31 which rod also carries a disk 42 at its lower end that is engaged by means of a coil spring 32 for normally exerting an upward pressure thereon. The latch 28 is carried within a casing 33 so as to protect the same against the water or moisture from the casing 1. The casing 33 is supported upon a bracket 34, said bracket 34 being suspended from the carbid tank 14 by means of a bracket 35. The bracket 34 is provided with a depending tubular casing 36 .which constitutes a housing for the spring 32. The bracket 34 is provided with notches 37 at its upper end and is engaged by means of the binding bolts 39 to constitute a sufficient securing means therefor.

A narrow casing 40 is positioned centrally of the carbid tank 14 and carries at its upper end a tubular casing 41 through which the operating rod 11 passes. The operating rod 11 carries a head 42 at its lower end for engaging the upper end of the rod 31 and pushing the same downwardly for releasing the valve 24 from the rubber washer 23 and allow the carbid to drop from the carbid tank 14. The narrow casing 40 is provided at its lower end with a flared flange 43 which is supported or spaced from the lower edge of the casing 14 by means of brackets 44. A cap 45 is carried by the rod 11 and is adapted, when the bell 6 is filled with gas to be drawn away from the lower edge of the tank 14 thereby allowing the carbid to fall in upon the top of the valve 24. This cap 45 is preferably of an elongated structure and carries a sealing tube 46 which constitutes means for producing an air tight closure for preventing the moisture from passing from the bell into the carbid holder. The tubular portion 41 is also provided with a sealing washer 47 for preventing the escape of moisture into the carbid holder through the tube 41.

The operation of the device is as follows: When the gas bell is filled with gas the operating rod 11 will be drawn upwardly thereby drawing the cap 45 upwardly and allowing the carbid to fall in upon the top of the valve 24 as just described. lVhen the gas within the bell is being used up and falls below a predetermined point, the bell G will descend thereby forcing the operating rod 11 downwardly and causing the head 42 to engage the upper end of the rod 31. At the same time the cap 45 will drop over the aperture 22 and prevent the further entrance of carbid under the cap. In this way a measured quantity of carbid will be assembled at the discharge mouth or opening for delivering the measured quantity of carbid to the water chamber in the lower end of the casing 1. As the bell (3 continues to descend, the rod 31 will be forced downwardly thereby causing the head to push the catch 28 from under the flange. 26 and thereby allow the valve 24 to be suddenly forced open and deliver the carbid to the water chamber in the bottom of the casing 1. \Vhen the gas is again generated to a suilicient amount the bell 6 will be again raised and the operating rod 11 will be pulled upwardly and re lieve the pressure from the rod whereupon the spring 32 will force the rod 31 upwardly carrying the valve 24 upwardly closing the discharge opening 22 and allowing the catch 28 to fit under the flange 26. The cap 45 will also be drawn upwardly and allow the carbid to fall upon the top of the valve 24.

A tube 48 extends longitudinally of the gas bell upon each side thereof and stops short of the lower end of the bell so as to allow the gas to pass off therethrough in case the gas bell should expand for too great an extent.

An air cock 49 is carried by the outer casing 1 so as to allow the operator filling the tank with water to determine as to when sufficient water has been placed therein for the water cock 49 may be left open and as soon as the water has reached the cock the water will begin to flow out therethrough, thereby notifying the operator that sufiicient water has been placed within the tank. A drain cock or plug 50 may be also placed at the lower end of the water seal chamber 51 as illustrated in Fig. 1.

It should be understood that the depending tube which is suspended from the lower end of the carbid container in which the coil spring is mounted may be filled or partly filled with oil to protect and lubricate the same.

It, of course, should be understood that if the hell 6 should fall too far down upon the carbid container 14 the bell may be pulled up sufficient by means of the handles carried by the top thereof so as to allow a funnel to be placed in the filling aperture of the carbid container 14.
